[0022] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the following will further describe the solutions of the present invention. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] The following will describe the peritoneal dialysis machine pipeline connection protection sleeve according to the embodiments of the present invention with reference to the drawings.

[0025] As Figure 1 shown, the peritoneal dialysis machine pipeline connection protection sleeve according to the embodiment of the present invention may include a sleeve 1, the sleeve 1 is sleeved on the peritoneal dialysis machine pipeline 4, and a fixed end 11 and a movable end 12 are provided on the sleeve 1.

[0026] Among them, the fixed end 11 is fixed on the peritoneal dialysis machine pipeline 4, and the movable end 12 can be pulled along the axial direction of the sleeve 1 to extend to the peritoneal dialysis tube communicating with the peritoneal dialysis machine pipeline 4.

[0027] It should be noted that the sleeve 1 is fixed to the peritoneal dialysis machine pipeline 4 before leaving the factory and is jointly sealed in a sterile bag, so as to improve the sterility of the sleeve 1 and further reduce the production cost without adding an additional sterile bag for packaging.

[0028] A fixed band 2, the fixed band 2 is provided on the sleeve 1, and the fixed band 2 is used to seal and fix the movable end 12 on the peritoneal dialysis tube.

[0029] Specifically, after the peritoneal dialysis machine pipeline 4 is connected to the peritoneal dialysis tube inserted into the patient, the movable end 12 of the sleeve 1 can be pulled along the axial direction of the sleeve 1 and extended to the peritoneal dialysis tube connected to the peritoneal dialysis machine pipeline 4. Subsequently, the movable end 12 can be quickly sealed and fixed on the peritoneal dialysis tube through the fixing belt 2, thus completing the covering and sealing of the connection between the peritoneal dialysis machine pipeline 4 and the peritoneal dialysis tube. The operation is simple, the closing is fast, the exposure time of the connection to the air is reduced, the asepticity is high, and the risk of infection of the patient during long-term treatment is effectively reduced, thereby improving the safety during the treatment period.

[0030] In an embodiment of the present invention, as Figure 1 shown, a plurality of pleated portions 10 are integrally formed on the sleeve 1, and the plurality of pleated portions 10 are outwardly protruding annular structures. The inner diameter of the pleated portion 10 is the same as the inner diameter of the sleeve 1, the outer diameter of the pleated portion 10 is larger than the outer diameter of the sleeve 1, and the pleated portion 10 can be compressed or extended axially on the sleeve 1.

[0031] It can be understood that the design of integrally forming the pleated portion 10 and the sleeve 1 enhances the overall structural strength of the sleeve 1, making it difficult for the pleated portion 10 to deform or fall off when the sleeve 1 is subjected to an external force, improving the stability of the pleated portion 10. At the same time, due to the seamless connection between the pleated portion 10 and the sleeve 1, the sealing performance between the two is further enhanced, effectively preventing the intrusion of external microorganisms, and improving the aseptic guarantee during the treatment process.

[0032] Specifically, when the movable end 12 is pulled, the pleated portion 10 will appropriately unfold along with the tensile force, thereby realizing the axial extension of the sleeve 1. This process ensures that the sleeve 1 can quickly and tightly cover the connection between the peritoneal dialysis machine pipeline 4 and the peritoneal dialysis tube.

[0033] Furthermore, as Figure 1 shown, the plurality of pleated portions 10 are axially distributed along the sleeve 1. Among them, the axial distribution enables the sleeve 1 to extend axially to ensure linearity and seal the connection between the peritoneal dialysis machine pipeline 4 and the peritoneal dialysis tube.

[0034] It should be noted that the plurality of pleated portions 10 described in this embodiment can be axially equally spaced along the sleeve 1 or arranged irregularly, and the number of the plurality of pleated portions 10 can be 2, 3, 4, 5, etc. There is no limitation here, and it can be selected according to the actual situation.

[0035] In an embodiment of the present invention, as Figure 1 shown, the sleeve 1 is arranged adjacent to the connection end of the peritoneal dialysis machine pipeline 4 and the peritoneal dialysis tube.

[0036] Among them, it can be understood that the above settings can reduce the number of the wrinkled parts 10, reduce the stretching length of the sleeve 1, and can also complete the covering and sealing of the connection between the peritoneal dialysis machine pipeline 4 and the peritoneal dialysis tube, so as to achieve the purpose of saving materials, and further reduce the production cost.

[0037] In an embodiment of the present utility model, as Figure 1 shown, both the sleeve 1 and the wrinkled part 10 are made of transparent plastic material. Among them, it can be understood that through the above settings, the state of the connection between the peritoneal dialysis machine pipeline 4 and the peritoneal dialysis tube can be observed by using its transparent characteristics, so as to facilitate observing whether there is looseness or disconnection and deal with it in time, thereby ensuring the continuity of treatment and the safety of patients. More importantly, the flexibility of the plastic material endows the wrinkled part 10 with the ability to extend. When needed, these wrinkled parts 10 can be easily stretched to adapt to different connection length requirements.

[0038] In an embodiment of the present utility model, as Figure 1 shown, the length of the fixing band 2 is at least wound around the movable end 12 for one week, and there is a part of the fixing band 2 protruding outside the sleeve 1.

[0039] Specifically, the design that the length of the fixing band 2 is at least wound around the movable end 12 for one week can completely wind and seal the movable end 12 for one week on the peritoneal dialysis tube, thereby improving the sealing performance at the fixing part of the movable end 12 and the peritoneal dialysis tube, effectively preventing the intrusion of external microorganisms, and enhancing the aseptic guarantee during the treatment process. Among them, the length of the fixing band 2 can be wound around the movable end 12 for one and a half weeks, two weeks, two and a half weeks, etc., which can be selected according to the actual situation.

[0040] At the same time, the area where the fixing band 2 protrudes outside the sleeve 1 can increase the contact area with the peritoneal dialysis tube, which can not only achieve the sealing performance at the connection and fixing part of the movable end 12 and the peritoneal dialysis tube, but also achieve the stability at the fixing part of the movable end 12 and the peritoneal dialysis tube, reducing the occurrence of looseness or detachment caused by patient movement or external factors.

[0041] In an embodiment of the present utility model, as Figure 1 shown, the fixing band 2 has an adhesive 20, and the adhesive 20 completely covers the surface of the fixing band 2.

[0042] Specifically, the adhesive 20 can be used to quickly bundle the fixing band 2 on the peritoneal dialysis tube to achieve the quick fixing and sealing of the movable end 12.

[0043] Furthermore, a release paper (not shown in the figure) is attached to the adhesive 20.

[0044] It should be noted that the release paper described in this embodiment is also called silicone oil paper or anti-sticking paper. The release paper is mainly used to effectively prevent adverse factors such as dust and impurities in the external environment from directly contacting the adhesive 20, thereby maintaining the cleanliness and adhesion performance of the adhesive 20, and avoiding the adhesive 20 from being covered with dust and affecting the adhesion. The release paper has good removability, and the release paper can be quickly torn off the adhesive 20 before being bonded and fixed by the adhesive 20.

[0045] In one embodiment of the present invention, Figure 1 As shown, the sleeve 1 is provided with a connecting belt 3 which can be torn and separated from the sleeve 1 along a preset path.

[0046] The preset path extends axially along the sleeve 1 and covers the plurality of folds 10 and other parts of the sleeve 1 except the folds 10 .

[0047] Specifically, after the APD treatment is completed, the nursing staff can tear off the connecting belt 3 to quickly and completely separate the sleeve 1, thereby separating the peritoneal dialysis machine pipeline 4 from the connection between the peritoneal dialysis tube, reducing the cumbersome disassembly process, facilitating the disassembly operation, making the operation simple and convenient, and reducing the possibility of contamination during operation.

[0048] Furthermore, if Figure 1 As shown, a protrusion 30 is provided on one end of the connecting belt 3 , and the protrusion 30 protrudes from the sleeve 1 .

[0049] Specifically, the provision of the convex head 30 provides a clear and stable point of force for the nursing staff, making it easier to apply force when the connecting belt 3 needs to be pulled for rapid tearing, thereby improving the convenience of operation.

[0050] In summary, the peritoneal dialysis machine pipeline connection protection sleeve of the embodiment of the utility model can quickly cover and protect the connection between the outlet pipeline of the peritoneal dialysis machine and the dialysis pipeline. It is easy to stick and has high sterility. It can effectively reduce the risk of infection in patients during long-term treatment, thereby improving safety during treatment.
